Abstract
ABSTRACTWelding is the most economical and efficient way to join metals permanently. It is the only way of joining two or more pieces of metal to make them act as a single piece. Friction stir welding (FSW) is a most versatile mechanical joining process. This joining Technique welds by using a rotating and non-consumable welding tool to locally soften a work piece, through heat produced by friction and plastic work, thereby allowing the tool to stir the joint surfaces. In this welding process, a rotating welding tool is driven into the material at the interface such as two adjoining plates, and then translated along the interface. The mechanical properties of aluminium alloy 6061 welded joints need to study before going to processing and preparing various mechanical components. Aluminium alloy 6061 welded specimens with suitable dimensions are prepared and these specimens are tested through various mechanical tests. These specimens are welded through friction stir welding process. FSW is an ideal process for producing low cost and high performance joints. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminium alloys and other metallic alloys that are hard to weld by conventional fusion welding. In this paper the evaluation of mechanical properties of aluminium alloy 6061(AA 6061) welded joints such as impact strength, hardness and compressive strength and also studied.Keywords : Friction stir welding , impact strength, aluminium alloy
